What would be the best ways to develop blue bioeconomy in the Baltic States? An online workshop on 26 November organised by Latvian Institute of Aquatic Ecology will try to answer this question through presentations and discussions. The workshop is an event of the "Blue Platform" project and registration with a draft agenda is available here -


In the framework of the Climate KIC programme "Pioneers into Practice" we had an opportunity to host Ms. Barbara Massalska at LIAE in October. Barbara is an organic geochemist working at the Polish Geological Institute. Her current research involves the reconstruction of primary producer communities in the Zechstein Sea (Permian) based on organic geochemical indices and biological markers. Microplastic pollution studies has been in her circle of  interest already a while ago. At the LIAE Barbara acquired sampling, preparation and analysis techniques used to study microplastic pollution for the assessment of freshwater ecosystems status and changes. We wish Barbara neverending success in applying the gained practical skills at future studies!

A new study just published at "Estuarine, Coastal and Shelf Science" states that probability distributions of different water levels have become narrower in 1991–2018 compared to 1961–1990 whereas very low water levels are now less frequent. LIAE's researcher Maija Viška together with Estonian colleagues has also found that the increase in water level on Latvian shores is slower than the global sea level rise. Congratulations to Maija on the published research! Full article is available here-


Project CWPharma of Interreg Baltic Sea region programme is moving towards its completion and the results are now available. Reports from work packages with active involvement of LIAE can be found here:

Hopefully the results will be applied to reduce content of pharmaceuticals in wastewaters!

To explain the myths and tell the truth about the Baltic Sea will be the main task of LIAE when taking part into the Gulf of Riga Regatta, starting on 28 June from Ventspils. Facts about pharmaceuticals in seawater, various pollutants and microplastics in our marine areas, as well as non-indigenous species will be presented at the event on 29 June. It will be possible also to taste a soup cooked from non-indigenous crabs and round gobies! More about regatta -

We are proud to announce that two new articles have been published in April and May containing LIAE's research results -

Latvian Institute of Aquatic Ecology has started implementation of the second PostDoc project -

"Development of early warning system for environmental health by using state-of-the-art ecotoxicological methods targeting reproductive variables in amphipods".

The project aims to identify biomarkers and eco-toxicological approach for detection of reproductive disorders in amphipods as screening tools and early warning system (EWS) for assessment of environmental quality in water.

The overall objective of the project is to adopt and implement novel approaches in the interdisciplinary field of biological indicators to predict and control the environmental quality in aquatic ecosystems – for the first time in Latvia.

The project is ERDF funded post-doctoral research (application No 

While most of scientific events have been cancelled or postponed Environmental toxicology and chemistry society - SETAC Europe has held its 30th Annual Meeting although for the first time as a virtual event. Online presentations and poster sessions were held at 3-7 May 2020 and LIAE took the advantage to participate with two poster presentations. Part of results by Interreg BSR project CWPharma were summarized in a poster "Biotests evaluate contaminants reduction via advanced waste water treatment" (presented I.Putna-Nīmane). The second poster "Determination of acute and chronic ecotoxicological effects of leachates from geosynthetics in different stages of artificial hydraulic engineering application process" included outcomes of ERA-Net RUS Plus project EI-GEO and of postodoctoral grant No. (presented by E. Strode).
Conference home page and virtual venue are available also now.
On 20 April 2017 Latvian Institute of Aquatic Ecology has started a field work phase of pilot investigation on sustainable and innovative use of marine resources as a task in the project "SmartBlueRegions". Two sets of three ropes as a substrate for settling and further growth of bivalves Dreissena polymorpha will be deployed in the Gulf of Riga near Zvejniekciems and Lapmežciems for testing. Bivalves are important players in the self-purification processes of the Baltic Sea water. #SmartBlueRegions, #SUBMARINER Network

Latvian Institute of Aquatic Ecology has organised the release of a new documentary "Baltic hitchhakers" depicting the spread of invasive species in the Baltic Sea via shipping. The creation of movie has been a task of the project COMPLETE, funded by Interreg Baltic Sea Region programme. Watch it here -
